Shotgun: Consistent, non-random spread. Several tight centered pellets, complemented buy several outer ring pellets. Centered pellets have infinite range while outer pellets dissipate past a few meters. Headshot capable at any range but ineffective at long unless the target is weakened or one-shot, otherwise requiring a beatdown or follow up shots.
Results in a shotgun no longer limited to short range if accurate with the center pellets, and no longer lacking nuance at close range, while still retaining important shotgun properties.
